Publication Abstract

Simple analytical results for bedload transport due to tides

J. Aldridge

Patterns of sediment erosion and deposition arising from tide induced bedload transport are examined using a simple analytic appraoch. A fairly general bedload formulation is used re-written in terms of an applied depth mean current. Decomposing the current into a principal ($M_2$) tidal constituent, an ($M_4$) first harmonic, and a tidal residual, it is straightforward to derive an expression for the contribution each makes to the integrated tidal flux. The results are applied to calculate the net erosion and deposition patterns for the case of a superposition of a Kelvin tidal wave, a harmonic overtide, and a residual tide.
